Petrol in a Diesel Car in Edenbridge: How Worried Should You Be?
Less than you likely are, provided it has not been started. Petrol sitting in a diesel tank does nothing to your motor until something draws it through your fuel system — the ignition priming your pump, your starter, or the drive itself. So the truthful answer to the first question anyone around Edenbridge asks, "have I wrecked it?", is generally no. Leave the motor off and call Petrol in Diesel — that is how you keep it that way. Keep reading for three things: the effect petrol has inside a diesel motor, the signs of how far it has spread, and ways to make sure you don't do it again.
Petrol in a diesel: what does it do to the engine?
Passing through a motor, diesel is doing two things at once. Before it combusts, it lubricates — then it combusts. The high-pressure fuel pump and your injectors are designed to very fine gaps, and your diesel passing through them is what keeps those surfaces from grinding against one another.
Petrol handles the first task badly and the second not at all. A pump running on a petrol blend is wearing itself out, since petrol is thinner than diesel and takes away the protection the fuel system relies on. Petrol is also made to resist igniting under compression — the opposite of what a diesel wants from its fuel — and that's where any rattling comes.
Seen together, they make clear what shape the issue takes. It's movement that does the harm, not contact. All a tank with petrol in it amounts to is a fuel fault. A pump that has been working on that petrol is the start of a mechanical one, and whatever a worn pump sheds moves on with your fuel to your injectors further on.
Four scenarios we see around Edenbridge: how bad is petrol in a diesel?
The best case there is: filled up, never started. Being at a forecourt is what makes this possible: elsewhere, the car has been driven there to begin with. With the petrol kept in that tank alone, it's drained and rinsed right where it stands, and nothing more is needed.
The ignition switched on, or a short start. Once primed, the system has pulled petrol from that tank as far as the filter and the lines. Still generally straightforward: drain, flush, and your filter sorted.
Those few miles driven meant the pump working on fuel weakened by petrol the whole way. How hard the vehicle was driven matters as much as how far, and this work takes in your tank, the fuel lines, your filter and fresh fuel through the whole system. Driving the kids to Edenbridge Primary School is one sort of trip. Any mileage on the M25, under 10 miles from Edenbridge, means the motor has worked hard throughout, and a run to Westminster, under 25 miles away, makes a very different job too.
Knocking, a lumpy idle, smoke, a throttle gone soft: driven until it complained. That is your engine telling you its fuel has stopped behaving like diesel. Leave it wherever it stops: a lay-by, a quiet street, the verge on High Street. Lasting damage is very unusual when a vehicle is stopped soon, and the fuel drain and flush that still go first sort it out.
Petrol in a diesel stories Edenbridge motorists hear
Myth: "Fill it the rest of the way with diesel and it will be fine." It will not. Topping up takes out nothing; it gives you a bigger tank of the same mix. Percentage is not how a diesel fuel system tolerates petrol, whatever that guidance assumes.
Myth: "A modern diesel can cope with a bit of petrol." If anything, the reverse. Protection counts more on newer diesels, not less, because their fuel runs through finer components at higher pressure.
This is the one that fools people. Myth: "If it starts and drives, there is no damage done." Any petrol engine fed diesel usually will not run, so the driver stops and the damage stops with them. A diesel fed petrol generally starts, idles and drives away as though nothing has happened, while the pump wears. Being able to run isn't the same as being fine.
"A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a different problem. What petrol has diluted stays diluted, and the petrol remains in your tank anyway.
"Drain it yourself and you're sorted" — a myth, because after it has been running some petrol sits in the filter and lines, waiting to go straight back through your pump at the next start. Also, a can of petrol filled by the roadside is truly hazardous.
Petrol in a diesel: how does it take place?
A careless moment is seldom the cause, and no one means to do it. The forecourt makes it easy: the petrol nozzle is the slimmer of the two, and it slides into a diesel filler with almost no resistance, whilst a diesel nozzle mostly will not go into a petrol car at all. So the mistake runs one way.
The moment routine stops matching the car is the moment it happens. Courtesy car, hire car, or a car that's brand new. Two cars on one driveway, one petrol, one diesel. Your usual forecourt, its pumps suddenly in a different order. Filling up in a hurry en route to Edenbridge Town, with a train to catch. A new-to-you diesel Peugeot 308, its first fuelling, and a driver used to petrol: exactly when it occurs. The hand repeats what it has always done when you add rain, a phone call or a back seat full of children.
Next time you fill up around Edenbridge: avoiding petrol in a diesel
- A green handle for unleaded and black for diesel is usual in the UK — but not on each forecourt. Trust the label on the petrol pump, not the colour.
- In a car you do not know, look inside the flap over the filler or at the cap before the first fill: many vehicles print the fuel there.
- Good intentions do less than a sticker or a fob in a vivid colour on the diesel's key when a household has one of each. So mark it.
- "Diesel", aloud, before you lift the nozzle — every time a new or hired car gets its first tank. It seems daft. It works.
- Whilst you're thinking about something else, this is an easy mistake to make — so put the phone away.
- Some diesels have a filler built to reject a petrol nozzle, and devices you can add exist for motors without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop reading the pump.
- Stop the moment you realise. Less petrol in that tank means a weaker blend. It does not change what to do next, which is still not to start it.
Put petrol in a diesel in Edenbridge already?
The order of things is brief, then. Leave it unstarted, with your ignition off as well. Still at the forecourt, at Gulf or anywhere else? Ask the staff to help you push the car away from the petrol pump. Next, 0333 366 0103. We will ask what got in, about how much, and if it has been run.
Say so if it was AdBlue rather than petrol: it's a separate problem, with its own page for Edenbridge, because AdBlue brings corrosion and deposits rather than lost lubrication.
Edenbridge petrol in a diesel jobs: why one costs more than another
There is no honest single quote for this, because the four scenarios above are four different tasks. What moves the cost is chiefly which of them you are in. Two things follow that: the petrol that went in as a proportion of what your tank takes, then the place your car is in and whether our van can reach it safely.
Three queries come first, before quoting, rather than after — what went in, how much, has it run — and that is the reason. Given the answers, you get a straight figure rather than a range.
